Default Power supply repair (Sun)

Slightly OT but certainly in the DIY realms ......
We have a Sun Fire V100 with a dead power supply (outside of warranty). The
Sun resellers report that we cannot buy a replacement one as Sun do not
offer one. Instead we would have to get a Sun engineer to come out and
replace it (and would cost an absolute fortune).
Does anyone know if there is a way of reparing these units?. We`ve had the
lid off the PSU and noticed there is a fuse hardwired to the board next to
the mains stepdown transformer- anyone know what rating this would be or if
there are any other components we should be checking ?

99 times out of 100 yoir problem will be a fuse, plus whatever caused it
to blow.
If you replace the main electrolytic - 400V rated - and the power
transistor, it should work.
Oh, and the fan probably siezed, which is why it blew.

When I read this, I thought coal, gas or log? :S

Then looking at the replies I realised what it is and thought of this:

There are some schematics available, so out with the soldering iron
and multimeter...

I have a Sun reseller contact if you want to drop me an e-mail.

I'm sure he can get one at a good price (or he will have one on the shelf)

Paul.
